Decoction - The Toast Test

Yeah, no kidding !  I brew way more than I can drink, and there’s no shortage of people ready to drain my leftovers. I don’t mind, I get to brew more often.

Not bad problems to have.

That’s a nice looking recipe. I think I will try it without the decoction and just use a direct heat step mash at those temps he lists. Any recommendations for the times at those temps?

I have had luck following Kai’s outline of the Hochkurz step mash.

Not trying to throw fuel on the decoction debate fire, but I’ve got a question:

What temperature does the decoction boil at?

I realize that “212 degrees at sea level on a standard day” would be the default answer…but doesn’t the presence of sugars perhaps raise that temperature? Consider candy making: as more water is boiled away from the sugar solution, the temperature increases. Granted, that is a MUCH thicker sugar solution than you’d likely find in a decoction boil, but the temperature should in theory still be higher.

Not enough sugar tpo make a real difference.

That’s about what I expected. What affect does starch/malt granules have on boiling temp?

again, not significant. especially because you should not have much starch in the boil.

I’ve measured the boiling temp of a 1.100 boiling wort at a handful of feet above sea level and the difference was a degree or two tops. That could be accounted for by difference in atmospheric pressure.

A 1.100 wort is about 24% sugar, and you can see that as you say only a few degrees higher. At my elevation (900 ft), that puts it up to about 212F, normally water boils at right about 210F here.

My friends are cyclical, when the beer dries up towards fall, so does the knock on the door.  I enjoy their faces when they take that sip.  One friend tells me how beer is his passion.  I disagree, his passion is drinking good “free” beer. 
As for the decoction debate, I guess I’m in the no thanks camp.  I tried decoction once, never felt the need to revisit.  I do love to read everyone’s experiences.  I would love to taste the results of a triangle test, just not produce the decoction.  The mess I made of the first attempt made me enjoy the complexity of my single infusion pils.
